FAQ
Q: What to do when a safety light curtain malfunctions?

A：
Safety light curtains are important safety devices used to protect workers and equipment. However, even high-quality safety light curtains may experience malfunctions. This article will discuss common safety light curtain malfunctions and provide troubleshooting solutions to help you resolve the issues promptly.

1. Safety light curtain not functioning properly

If the safety light curtain is not functioning properly, first check if the power supply is working correctly. Ensure that the power cable is connected properly and check if the indicator lights on the light curtain are illuminated. If the indicator lights are on, it may indicate a power supply issue that requires either replacing the power supply or repairing the power cable.

Additionally, check the connection between the emitter and receiver of the light curtain to ensure it is secure. Sometimes, the connection may become loose or disconnected, resulting in the failure to transmit light signals. Reconnect the emitter and receiver, ensuring a secure connection.

2. False alarms from safety light curtain

If the safety light curtain is frequently producing false alarms, meaning it signals an alert even when no objects or personnel are entering, it may be experiencing interference. First, check the surrounding environment for any reflective objects or bright light sources. These objects or light sources can interfere with the proper operation of the light curtain.

Additionally, check if there are any obstacles blocking the transmission of light between the emitter and receiver of the light curtain. If there are objects or dust obstructing the transmission of light, remove them or reinstall the light curtain to ensure smooth light transmission.

3. Sensitivity issues with safety light curtain

If the sensitivity of the safety light curtain is either too high or too low, meaning it fails to produce an alert signal when obstacles are present, it may require adjusting the sensitivity settings. Refer to the user manual of the light curtain to learn how to adjust its sensitivity.

While adjusting the sensitivity, you can try gradually increasing or decreasing the sensitivity settings until you achieve the desired alert effect. If the issue persists, it may be necessary to check if the receiver of the safety light curtain is damaged or needs replacement.

For more complex malfunctions, it is recommended to seek assistance from professional technical support personnel for inspection and repair. They have extensive experience and expertise that can help you quickly resolve the issues with your safety light curtain.

In summary, when a safety light curtain malfunctions, first check if the power supply is working properly, and ensure that the connection between the light emitter and receiver is secure. If there are false alarms or sensitivity issues, settings can be adjusted or obstructions can be cleared. For complex malfunctions, it is recommended to seek professional technical support. Ensuring the proper functioning of the safety light curtain is crucial for protecting the safety of workers and equipment.
